I would upload all executable files to Virustotal.com because the website uses the most popular scanners and offers an impression of how the game will be handled after the release.
Now you have to wait about a week and then check your files again(because usually the submitted files will be forwarded to the anti-virus companies and checked again more carefully).
If there are any false-positives after the week, you have to contact the company behind the scanner, for Example http://support.kaspe...b/helpdesk.html for the Kaspersky Scanners.

Has anyone experience with the effect of signing executables with false-positives?
